WHEEL.

To all whom/t may concern." .u

lle it known that I, `W1LLIAM Siemen, a citizen ci the United States,residing at Chicago, county oiCook, and State of Illinois, have inventedcertain new and useful Improvements in l/Vheels, oitwhich the followingis a specification.

This invention relates to an improved vehicle wheel, the principalobjects being simplicity, cheapness, lightness, strength, andresiliency. Numerous other objects are in contemplation as well, as willmore fully hereinafter appear from the specification p and claims, andfrom the accompanying Figure 1 is a side view of a wheel embodying myinvention, `one casing section and one cushioning element being removedto exhibit certain of the interior parts;

The suggested embodiment of my present wheel shown in Fig. 1 employs twocomplement-ary casing sections` 11 arranged to pro` vide between them achambered space within which certain resilient elements are contained.Each casing section is shaped to provide a peripheral flange 12 adaptedto receive reinforcing angle rings 13 upon which are mounted divided rimsections 14, such, for example, as are shown in Figs. 2 and 3. Flanges15 are formed on the rim sections to grip a tire casing 16. The rim,tire flange, and tire construction may obviously be varied to suitrequirements, an

i alternate arrangement being reserved for consideration in connectionwith Figs. 9 and 1.0, presently to he described.

Specification of Letters Patent.

is a similar view, taken on line 1n Fig. 2, consists ofV two`complement-ary sections conveniently secured together as by bolts 20'(see Fig. 1). The casingsections are also held in unitary relationbysome such device as tie bolts 21\ locatedat convement intervals.Extending radially from the hub are spokes 22 whose inner "ends may beappropriately conligured,as by means of grooves 23, to enter` intolocking engagement with `the hub which is formed with` co# operatingelements 24 for this purpose. The outer end of each spoke may be in the`form of an eye 25, through which extends a circular core piece 26occupying a central position within the peripheral channel 17,"each ispoke eye 25 being preferably welded to the core piece..`

The parts thus far described include a hub which is loose with respectto the wheel casing, and a series of spokeslixed to the hub and to thecore piece which lies within the peripheral channel or' the casing. The`remaining wheel parts are formed from some material havingresilientproperties, such, for example, as rubber, or a rubbercomposition, and include a plurality of elements 27 1 equal in `numberto the number of spokes, each element -being in the general form of theletter l-l with a straight connecting portion 28, the remaining portions29 and I30 being each shaped in the form of an arc struck from a commoncenter. The straight portions 28 of `these resilient elements 27 arearranged to lie within the spoke channels 18, the arcportions 29 withinthe peripheral channel 17 and the other arc portion 30 within theannular channel adjacent the hub. As will appear from the severalligures of the drawing, the resilient elements 27 are formed around thespokes 22 and the core piece 26this being accent plished either by theprocess oifmolding, or by forming each element of two sections held incomplementary relation when posi` and at the same time be tree tooperate with `rmentari sept. a, 1919.

greater freedom, annular channels 31 are provided exteriorly thereof(see Figs. l and 2), and pockets 32 interiorly thereof, the pockets andchannels being preferably arranged in alternate order.

Referring now to the construction shown in Figs. 8, 9, and l0, it willbe noted that the Wheel is in all substantial respects the same as thedevice shown in Fig. l. Accordingly I have designated the casingsections, the interior channels, resilient elements, etc., by the samenumerals as those applied to the corresponding parts of the wheelalready described. The principal point of departure is in the tire rimwhich dispenses with the reinforcing angle rings. Asbest shown in Fig.9the casing Hanges 13 form the elly on which the tire is mounted,demonntable rims 33 being secured tozthe sides of the casing section bymeans of the tie-'bolts 2l. Each of these demountable rims is Jformedwith a tire retaining flange 34C and a casing engaging fiange 35 aroundwhich fits a ring 86. It is apparent that the tire flanges may beremoved by simply unscrewing the nuts from the bolts 21, whereupon therings 36 may be taken ott, permitting the tire rims 33 to be demounted.f

The present wheel is characterized by certain interior channels formedadjacent its periphery, adjacent its hub, and in the spokes, and by thepresence of resilient elements Within these channels tending to keep thehub centered with respect to the wheel periphery. This construction issuch that shocks and -bumps are easily and effectively absorbed withoutthe necessity of an air cushion in the tire or elsewhere.

I claim:

1. A vehicle wheel comprising, in combination, a hollow casing, a hubmovable radi- Copies of this patent may be obtained for ally of theeasing, means for ceutralizing the hub relative to the wheel consistingolt a plurality of spokes lixedly secured to the hub and radiallyextending therefrom, a ring-shaped member loosely arranged within thewheel casing in proximity to its rim and connected with each of thespokes, and a plurality of resilient elements surrounding thering-shaped member and spokes and extending into the hub for norinallymaintaining the hub in a position centrally oil the wheel, substantiallyas described.

2. A vehicle wheel comprising, in combination, complementary sectionsarranged to provide between them a peripheral rim channel, spokechannels connecting therewith, and a circular channel opening toward thecenter of the wheel, a hub disposed hetween the wheel sections andslightly overlapped thereby, spokes secured to the hub and extendedthrough the spoke channels, a core extending within the peripheralchannel and connected with each spoke, and re silient elementsinterposed between the huh and the Walls composing the various channelswithin the whcel, substantially as described.

3. A vehicle wheel coniprising, in combination, a rim, a hub, and spokesextended between the rim and hu'b, the spokes heilig fixedly secured tothe hub and loosely secured to the rim, there being intercomnnmieatingchannels formed in the rim, spokes, and hub, and resilient elementspositioned within the communicating channels, and extending rom the rimthrough the spokes into the hub and tending to centralize the hub withrespect to the wheel, substantially as described.
